Abstract
A semiconductor chip includes a semiconductor device connected between a first node to which a power supply voltage is applied and a second node to which a ground voltage is applied, a first ring oscillator connected to the first node through a first supply switch and the second node through a first ground switch and a second ring oscillator connected to the first node through a second supply switch and the second node through a second ground switch, wherein the first supply and ground switches are configured to operate in response to a first control signal, thereby operating the first ring oscillator, and the second supply and ground switches are configured to operate in response to a second control signal, thereby operating the second ring oscillator.
